GPS is a satellite navigation system that sends location information (latitude, longitude) to our device. In terms of GPS reception, being in an enclosed, dense space will prevent the GPS device from receiving GPS signals from the satellites. In terms of GPS accuracy, urban buildings (cities), valleys and mountain slopes can block and/or weaken the GPS signals. When weak signals are received, they may have been reflected off buildings and the surrounding landscape. This results in an inaccurately calculated position. Insufficient GPS signal also tends to have a considerable impact on battery depletion.
If you enable the optional GPS as a location method on the Tive Platform, the tracker will attempt to acquire the GPS satellite signals as a method of location. However, if it cannot detect enough GPS satellites, it will utilize fallback methods using nearby cell towers instead or the nearby Wi-Fi access points (if enabled). Below is the approximate accuracy for each location method.
- Satellite/GPS : 20 m (70 feet)
- Wi-Fi Geolocation: 50 to 100 m (<200 feet)
- Cellular Towers Triangulation: 500m (0.3 miles)
For best results, we suggest using GPS positioning in relatively shorter, over-the-road shipments. The placement of the tracker is critical to increase the chance of getting GPS satellite signals. For best performance, we recommend placing the tracker on the last pallet positioned near the door as high as possible as shown below.
